Hello @po-0500 ,As a partner you can Distribute plugins through Microsoft Partner Center. Ensure your app meets validation criteria for Teams apps used as plugins for Microsoft Copilot, then submit your app package to Microsoft Partner Center through the Microsoft 365 and Copilot program. Once validated and approved by Microsoft, your plugin will be an active offer in the Microsoft Commercial Marketplace and ready for IT enablement. Once enabled by an IT administrator, it will appear in the Works with Copilot category of the Store within Microsoft Teams. Once deployed by an admin or acquired by a user, it will then appear as an installed plugin of Microsoft 365 Chat. Additionally, refer to Monetize your app. At the tenant level Plugins can be enabled and disabled, tenant Administrator can Enable or disable Copilot extensibility.
Hope this helps.
